Job categories
Primary - gathering materials from the Earth e.g. mining for coal, growing wheat or fishing.
Secondary - turning materials into things to sell. E.g. metals into car bodies.
Tertiary / service - you provide a service for people e.g. teach them, look after them when they’re ill, drive a taxi
Quaternary - High tech research. E.g. to develop a new medicine or do research into ICT.
Decline of farming
Lots of farms have gone out of business, this is because the money that is available to help them are being cut, and because competition from supermarkets is driving prices down/
High house prices
In some villages, up to 50% of the houses are owned as second homes. This means that during the week/ winter they are like “ghost towns” and local services like shops and pubs don’t have enough customers to survive.
Loss of services
Many people living in rural areas depend on the services there i.e. shops, post office, doctors. If people move away from the area they may not have enough customers to survive and might have to close.
Rural depopulation
There are a lack of job opportunities in rural areas, and those jobs that there are pay low wages. This means that people often have to leave rural areas - in particular young people. This is called ‘brain drain’. This causes a vicious circle, where as people leave services in villages might close down.

Erosion
The removal of parts of the lands surface. It is caused by rivers, wind , water and ice.
Hydraulic action
The force of water against the rock surface can cause air to be trapped in cracks. The pressure weakens the rock and gradually wears it away.
Abrasion
Stones and rocks are thrown at the rock surface. They scrape along a rock surface. This action is like sandpaper.
Attrition
Rocks and stones knock together and wear each other away.
Solution
Water dissolves the surface of a rock
Weathering
The slow break down of rocks on the Earth’s surface. It is caused by weather conditions such as rain or changes in temperature and sometimes plants and animals.
Biological
Burrowing animals such as rabbits can burrow into a crack in a rock, making it bigger and splitting the rock. Plant roots can grow in cracks, opening the cracks in the rock.
Chemical
Rainwater is slightly acidic because carbon dioxide from the air dissolves in it. Minerals in the rock may react with the rainwater, causing the rock to be weathered.
Mechanical/physical
Water gets into a crack in a rock and then freezes; it expands and pushes the crack further apart. When the ice melts, water gets further into the crack. The processes repeats. This is called freeze-thaw weathering.
